Problems in browser

I have Comodo Dragon browser 4.1.1.12. But when I set the browser for the first time, he placed a very long time and eventually ran out the error. Now I can not fix them and I can not remove himself browser. What should I do? :frowning: ???

There a video with problems:

I do not have any program that would prohibit the establishment and / or modify registry keys, so I do not know what was going on.
